Welcome to my website!

  • I’m an applied environmental economist focusing on two major environmental issues, ambient air pollution and climate change.

  • I’m an Assistant Professor at CREST and ENSAE in Paris. I’m also a research affiliate at the IFS, Misum and the IPP.

  • My current research seeks to answer three broad questions, mostly in the European context:
    1. What are the societal costs of air pollution? including health and non-health effects.
    2. To what extent do climate policies deliver health co-benefits? with an emphasis on the transport and electricity sectors.
    3. What are the determinants of support for green policies? with an emphasis on social norms and identity.
  • I completed my PhD at the Paris School of Economics and CIRED. I received the 2022 Best Doctoral Dissertation Award from the European Association of Environmental and Resource Economists (EAERE).
